We were extremely pleased with our stay at Nectar. From our first contact with the proprieter, Margarida, everything was easy and pleasant. Margarida was proactive in giving us information on getting to the B&B from the airport, she was amenable to our hour of arrival and she was always very friendly. The location of the B&B is really central, close to various public transport options and within walking distance of many restaurants/bars etc. Our room was a good size, the bed was comfortable, and everything was very clean. I particularly enjoyed the breakfast provided each morning in a separate dining room - coffee and steamed milk, bottled water, bread rolls and croissants, various types of cheese, ham, scrambled eggs and this really yummy pumpkin jam (which I would never have guessed was pumpkin. It was delicious).
The B&B is affiliated with Nectar Wine bar (which is run by the same people, and which is downstairs from the B&B). We didn't actually eat or drink at the bar, but other people have reviewed it favourably on this website. Noise coming from the bar was never a problem when we were in our room.
If there's anything I would have preferred was different ... nothing really stands out. It was a great experience and I would gladly stay there again or recommend it to friends.
